BAV70

BAV70 is the Changjing (JSCJ) dual common-cathode switching diode in SOT-23, package marking A4, AEC-Q101 qualified, verified against the maker’s AD-BAV70 datasheet (the AD- prefix is JSCJ’s document series; the orderable type is the bare BAV70). Verified figures are Changjing’s own: a peak repetitive reverse voltage of 70 V, maximum forward current of 200 mA, surge forward current of 2 A, forward voltage of 0.715 V maximum at 1 mA and 1.25 V maximum at 150 mA, reverse current of 2.5 µA maximum at 70 V, total capacitance of 1.5 pF maximum, reverse recovery time of 6 ns maximum, and power dissipation of 225 mW. The selection point is two fast common-cathode diodes in one SOT-23 for steering, clipping and protection in high-speed signal paths, with an automotive-qualified sheet behind it. Selection advice: keep the maker’s rating straight — the BAV70 designation is also documented by Nexperia, whose BAV70,215 elsewhere in this catalog is a 100 V row; this Changjing type is a 70 V class device, and the two makers’ tables must not be read across. Parameters verified against the Changjing AD-BAV70 datasheet.
